NTSB says trains not speeding before Okla. wreck

Three Union Pacific employees died in the June 24 accident near Goodwell. Another worker jumped to safety.

A preliminary NTSB report issued Monday said an eastbound train was traveling at 64 mph at the time of the crash and that a westbound train was traveling at 38 mph. The speed limit in the area is 70 mph.

Data couldn't be recovered from the lead locomotives, but the NTSB says it retrieved recorders from engines helping to push the trains. The agency said it is checking the data to see whether train operators were receiving signals properly.
